我国经历了改革开放30多年的经济增长奇迹之后，经济发展进入结构性减速时期，并联动引起社会、文化、空间发展的全面转型。由此，城市发展进入“增量扩张”向“存量优化”的变革期。2010年前后，在资源环境紧约束背景下，为了促进城市功能提升、产业解构优化、人居环境改善等，广州、深圳、上海、北京、南京等很多大城市积极开展城市更新工作，在城市更新制度建设、规划编制、更新管理等方面取得重大进展。论文选取广州、深圳、上海三个城市作为研究对象，通过比较研究，对三地的城市更新制度建设、《城市更新办法》及其配套文件和城市更新实践等开展深入研究。研究以广州、深圳、上海的城市更新政策为切入点，思考不同政策环境对城市更新制度建设的影响；梳理三地核心政策演进，挖掘三地城市更新制度的形成过程与政策选择的原因；剖析三地《城市更新办法》的内容，理清三地城市更新的思路；构建三地的城市更新制度体系，对比三地在机构设置、更新管理、规划编制、空间管控、政策体系的异同；总结三地更新实施情况与实施路径，得出三地城市更新制度建设的挑战与反思。论文通过对广州、深圳、上海城市更新制度建设的交叉比较研究，揭示当前我国代表性城市的城市更新制度建设的具体进展、创新成就、潜在问题及改进方向等，总结三地在城市更新制度建设过程中的经验得失，以及城市更新制度创新过程中可能存在的制度瓶颈，以期为各地的城市更新制度建设提供参考，为新时期破解城市更新难题提供方向指引和经验借鉴。

After experiencing the 30-year growth miracle of Reform and Opening Up, China’s economic development has entered a period of structural deceleration, and this has caused a comprehensive transformation of social, cultural and spatial development. As a result, urban development has entered a period of transformation from "physical expansion" to "built-up area improvement." Around 2010, under the environment of constraining on resources , many major cities such as Guangzhou, Shenzhen, Shanghai, Beijing and Nanjing have actively carried out policies to enhance urban functions, optimize the industrial structure, and improve the living environment; these cities have made significant progress in the construction of urban regeneration institution, planning, and management.This research select three cities of Guangzhou, Shenzhen, and Shanghai as the research subjects. The urban regeneration institution construction, urban regeneration methods, supporting documents, and urban regeneration practices of the three cities are deeply studied through comparison. It takes the urban regeneration policies of Guangzhou, Shenzhen, and Shanghai as the break through point to analyze the impact of different policy environments on the construction of urban regeneration institution; analyze the urban regeneration methods and clarify the thinking of urban regeneration in the three cities; explore the formation of the urban regeneration institution , the evolution of the core policies in the three cities and the reasons for choosing these policies; compare the differences in institutional settings, urban regeneration management, planning, space management, and policy systems among the three cities; and summarize the implementation status of urban regeneration, and the challenges and reflections on the urban regeneration institution construction in the three cities.Through the cross-comparison of the urban regeneration institution in Guangzhou, Shenzhen, and Shanghai, the research reveals the concrete progress, innovative achievements, potential problems, and directions for improvement of the urban regeneration institution in representative cities in China, and summarizes the experience of the three cities in urban regeneration institution construction, and the possible institutional constriction such institution innovation. The essay aims to to provide reference for urban regeneration institution construction in various places, and proposes directions and references for cracking down on urban regeneration problems in the new era.
